Today I will talk a little about meals and entertainment. Taking your client out to lunch or a ball game is a 50% deductible expense. You have certain rules to follow to get the deduction, including documentation of the meeting or the event, what business was discussed, etc. Here is a link that breaks it all down:

Some people like to keep a calendar of lunch meetings with clients, attach the receipt for lunch and write down what the lunch meeting was about. Or get out the old scanner and set up a folder on your computer; just write the info on the receipt and scan it in.
This is an area the IRS looks at during a lot of business audits, so documentation is important, especially if you have a large deduction.
